This is a great "mom" mystery. It's a great mystery, because it is so well written, that up until the end, you don't even know who is dead, let alone who the killer is. It's a great "mom" book, because it opens with the homicide detectives arriving at a Parent Association event, and throughout the novel, you read the viewpoints of various parents and school staffers as they explain events that led to the death. Seemingly insignificant events, like cupcake wars between moms who think cupcakes at class birthday parties are a rite of childhood, and fit moms who think only nutritious foods should be served; dads arguing over standardized tests; kindergartners being excluded from playdates and birthday parties; moms competing to throw the best birthday parties; and Parent Association officers drunk with power. Best of all, is the title, Big Little Lies, which begs the question, aren't all lies big lies?
